1 Samuel 11:6-7

Then the Spirit of God came powerfully upon Saul, and he became very angry. He took two oxen and cut them into pieces and sent the messengers to carry them throughout Israel with this message: “This is what will happen to the oxen of anyone who refuses to follow Saul and Samuel into battle!” And the LORD made the people afraid of Saul’s anger, and all of them came out together as one.
